Ecoparque João Pessoa Landfill Gas Project

Audit Analysis

The Ecoparque João Pessoa Landfill Gas Project is a VVB-verified methane avoidance project with a measured baseline and confirmed additionality, but it is undermined by 14 material findings, a direct contradiction on whether leakage was quantified, a grid emission factor discrepancy within the same monitoring report, and the absence of FPIC. The project's inherent low reversal risk as a landfill gas capture scheme is a structural positive, yet the volume of documentation errors and the unresolved leakage question create meaningful over-crediting and data-reliability concerns.

Project Description

Red Flags

• ⚠Two verification reports (Feb 2024 and Jul 2024) directly contradict each other on whether leakage was quantified or not addressed, leaving the 0% leakage deduction without a defensible justification
• ⚠The monitoring report (Oct 2024) contains two different grid emission factor values (0.3984 and 0.1017) for the same period, creating uncertainty in the ER calculation
• ⚠14 material findings were identified by the VVB, including incorrect ex-ante and ex-post parameter values, a calibration delay for the CH4/O2 gas analyzer, and non-conforming safeguards reporting
• ⚠Free, Prior and Informed Consent (FPIC) was not conducted, despite the project operating in a Brazilian community context
• ⚠The CDM PDD submitted for the Gold Standard transition is not the latest approved version under the CDM, raising questions about the accuracy of the transition documentation
